Abstract
Parallel ribs are aligned and clamped onto a vertical spine, which is a slow-wave discrete-element torsional transmission line. The spine is attached to a motor which may remain ON for extended periods or which be operated by a chip or other mechanical or electronic means which turns the motor ON and OFF at variable intervals, causing the spine to twist, affecting an apparent spiral motion through the length of spine as the ribs rotate. The motor ON and OFF sequencing is set to coordinate with the length and material of the spine and the attached ribs and weights.
Claims14
A mobile comprising:
- an elastic spine having a length extending between a first spine end and a second spine end,
- a plurality of ribs spaced apart along the length of the spine, each rib having a long dimension extending between a first rib end and a second rib end where each rib is attached to the spine between the first rib end and the second rib end,
- a motor connected to the spine at the first spine end for rotating the spine and the attached ribs to cause the ribs to torque the spine and cause patterns to propagate along the length of the spine.
